In 1934, Lola was on top of the world. Dubbed "The Siren" by MGM, she was a protégé of Louis B. Mayer, the original talkie sex symbol before the rise of stars like Carole Lombard and Jean Harlow. But like Harlow, Lola Grayson had a dominant stage mother and bad health that struggled to meet the demand of the Golden Age of Hollywood. Exploited, pushed, primped, and promoted as MGM's biggest star, Lola Grayson made one fatal mistake—falling in love with fellow MGM star Robert Taggart. Together, they were the golden couple that audiences demanded to see. But Lola wanted what every young woman at the time wanted - a husband and a family. For a major star, that was a death sentence.
In the present day, Joey Cabot is a novelist with a struggling career. In a stroke of fate, she purchases Lola Grayson and Robert Taggart's former home in Los Angeles. It was a secret love nest they kept hidden from the world, but what comes out of the old walls is a secret no one wanted to see the light of day. Something so explosive that it could lay Hollywood history wide-open. In discovering that secret, Joey sees the salvation of her career, but it soon becomes apparent that Joey isn't working for her salvation, but for Lola's.
